“On Cyber Monday, retailers deliver online discounts unlike any other day of the year — driving consumers to shop online no matter where they are or what device they’re shopping from,” NRF president and CEO Matthew Shay said in a release Sunday. “Millions of consumers shopped over Thanksgiving weekend and reserved a portion of their budgets exclusively for Cyber Monday, knowing that there will be digital deals that are too good to pass up.”

When it comes to Cyber Monday heavy hitters, e-tailing giant Amazon.com Inc. is once again leading the pack, offering more than 75,000 sales starting Monday and throughout the rest of the week on a range of products.

Go-to brick-and-click retailers Wal-Mart Stores Inc. and Target Corp. are also offering up their usual array of discount, slashing price on electronics and toys and other merchandise.

A number of retailers are extending deals beyond Cyber Monday. Macy’s Inc., for example, is hosting Cyber Week, with deals in-store on clothes, shoes, accessories all week long.

Kohl’s Corp. started its Cyber Days sale on Sunday, and it runs through Wednesday. The retailer is discounting variety of merchandise, including select products from Nike Inc.

Luxury stores are also in on the deals, Lord & Taylor is offering shoppers 25 percent off site-wide and free shipping on all online orders, as well as online-only specials today.
